The base y12 of theengine is pivotally supported yforhorizontal rotation onthe support 10 by meansofan upright vshaft `or post Patented. iiiaye, i922.Y

co'I

13. Supported on'the base 12 is a suitable hoisting mechanism 14', 'including drums and suitable `connecting vparts of 'ordinary con'- struction, whichv inv themselves tornino part of lily-invention.

I provide 'in connection with'the engine, a dumping struct-ure, comprising spaced uprights 15. rllhe uprights 15 are connected at their. upper ends by across member 16. Connected with the lower endsrnoi the uprights 15 vand extending rearwardly therefrom and inclined away :trom each other are frame members 17. l

The-v frame-'members- 17 and 15 are supported ony traction devices, such as skidslli. v-

ln the ends of the skids 18' are rings or the like 19 to 'which a tractor or team oit horses may be connected tor moving the dump from place toplace.` f y f Extending from the braces 15 approximately midway oi their height downwardly and rearwardly to the rear skid 18 are brace frame members 20.v Connecting the rear ends'of thevmembers 17 and the upper portions of the members 15 yare brace members 21. Connected with the upper portions of the members 15 and inclined downwardly andv outwardlyA therefromfto the forward skid 18 are frame members 22. l

Vertical supporting: members 22? are provided' which are xed to the frame members 17 and to brace members 2l. The supports 22a are bolted to the cross bar 22b which is fixed to the members 2O and supports the ioor structure hereafterl described.

Supported on the frame members 2O is an inclined runway or floor or the like 23,V eX- tending` from the rear skid upwardly to the central portions of the members 15, and thence inclined downwardly and forwardly, as at 24. rllhe portion 24 forms the bottom of a hopper, having the sides 25. Connected with the upper portions of the forward ends of the sides 25 by hinges 2-6 is a closure member 27. A spring` clip catch device 28 is se cured to the member 24 and adapted to lock the closure device 27 in closed position.

have provided in connection with the engine and the dump a slip or scraper 29, having at its rear portion the raised side members fill. Extending` rearwardly from the slip 29 is a handle 3l., whiclrmay be 'bent to different positions. lThe handle is of such material. and so attached that it may be bent by manual operation. Such bending, is, of course, done only infrequently. A brace 32 is conected with the bottom of the slip 29 and with U bolt clamp 33 onl the arms of which are nuts 34.

By loosening the nuts 34 vand bending the handle 3l to different positions, and then tightening the nuts 84, the handle may be locked in various adjusted positions.

The sides of the slip 29 are each provided with a series of holes 35 to receive bolts 36 and 37. Connected with the bolt 36 is a forwardly extending bail 38, at the ,forward central portion of which is mounted a pulley 39.

Extended rearwardly from the slip and pivotally mounted on the bolts 36 is a rear bail 40. Connected withy each bolt 37 is a brace 41 extendingq forwardly and inclined away from the wall of the slip and mounted on the adjacent bolt 36 between the arms of the bails 38 and 40, as clearly illustrated in Figure 8.

Secured to the upper part of the dump approximately directly above and slightly forwardly of the'bend in the floor or the like is a pulley frame 42, in which is mounted a pulley Connected with the pulley frame- 42 is a rope or cable or the like 44, which entends from the frame 42 around the pulley 39, thence upwardly and around the pulley and vthence to the hoisting,T mechanism 14. i

The placing of the pulley a short distance forwardly of the bend in the floor will make .possible to easily dump the load from the 1p. 1

Connected with the bail is a cable 45, which is connected to the hoisting mecha-y nism i4.

l ln Figure14', l have shown .a slightly different form of slip 46, having at its rear portion, an upwardly extending back member 47. Connected with the sides of the slip 46 is a suitable bail 48, ona which is a pulley 49 around which the cable 44 may be eX- tended. n

Connected with the rear part of the slip 46 are handles 50. Connected with the sides of the slip 46 forwardly of the points of connection ofthe bail 48 are cables 51, which are connected with the cable 45. The handles 50 are connected with the side walls of the slip 46 at such points as to form stops for limitingv the rearward, swinging movement of the bail 48.

f 1n the practical use of my improved dumping;` device, the dump and the engine are properly located and the engine may then be run for dragging` the slip toward the dump. '.l he slip is first pulled away from the dump by means of the cable 45 to position near the engine.

The engineer can then hold the handle of the slip, and after the enginey has been started for loading the; slip, lhema-y then release the handles and remain near the engine for controlling it.

The slip is drawn toward the dump and will travel up the floor 23` until it stands above thebend in the floor 23 and moves to position where the greater. part of the load is slightly forwardly of the bend, when the slip will automatically move to dumping position.

lt will be noted that the bolts 36 are located rearwardly of the center of V,0 ;ravity of the loaded slip, sok that when theislip is in position for dischargingthe load will be forwardly of the bolts 36 and the pull upwardly on the bolts 36 will tend to dump the load into the hopper. n

For handling` different kinds of dirt and gravel -the bolts 36 and 37 are adjusted rearwardly or forwardly, as desired, and mounted in different holes 35. i

lt will be noted that by connecting the rope or cable 45 with the frame 42 and then extending it around the pulley 39 or 49, as the case may be, and thence around the pulley 42, the greater part of the pull on the dump will be in line as nearly as possible parallel with the brace members 20 and also the brace members 21, so that with this arrangement, there is less tendency to upset the dump than is the case where the rope is connected with the bail 38 and thence extended aronnd the pulley 42 to the hoisting mechanism. I Attention is called to the advantager of leaving the engine at the center ofa circle, and the arranging of the dump at the out side of the circle and mounting it on skids and traction devices, whereby it may be moved around the circle.

' shown in Figure 4,

, mounted a pulley wheely 59.

*of dirt and sand of the load is :taken at the outside of the circle nearest the pointof' discharge. It will also be noted by 'the arrangement ust mentione'dthat the slip at thev time VVof loading is near the engine, so that one man can handle the slip and also operate the engine.. Y

The points of connection of the bail-38 with the slip 29 may bevaried by mounting the bolts 36 in different holes 35 for accommodating' the devicev to differentkinds andpgravel, for insuring the automatic dumping, when the slip is drawn to the upper portion of the floor 23. An extension 52wmay be provided at the lower end of the i i hole has been dug the dump.

It will be noted that the parts are so arranged in the modified form of the slip, that when the dumping action occurs and the slip tilts forwardly at the upper portion of the floor 23, the handles 50 will serve as stops to engage the arms ofthe bail 48 for dumping position. y

It will. also be noted that on account of the locating yof the pointsof'connection between the bail` 48 and the slip 46 rearwardly between the engine and yof the points of connection of the cables 5.1

withthe vslip 46, when lthe slip reaches its upper position at the upper portion of the vforward portion 23. the

cable 45 Vmay be held taut' and the cable 44 pulled forv raising the rear end ofthe slip andVv insuring proper dumping or dischargingaction. f

In Figures 6 and`7 I have shown mechanism for varying' the line of travel of the slip relative to the hoisting and Adumping mechanism. N Fixed vto the base 10 of the hoisting mechanismV is `a bracket or supporting member 53 in'which is 'pivotally mounted the arm 54 on the pivot 55. rlhe pivot y55 is received-within the opening in the support 53.

A plate 56 is fixed to the pivot 55 and is boltedy to the arm 54 by means of the bolts 57. This forms a substantial rigid bearing.

Extending upwardly from the plate 56 is the shoit shaft 58 on which is rotatably 0n the foi'- extending end ofthe arm -54 is the pulley wheel 60 mounted on the shaft 6l.

The return cable 45 which is fixed to the hoisting apparatus 14 and to the scraper or slip 29 is passed around ythe pulley wheels 60 and 59, as illustrated in Figures 6 and 7 of the drawings.

Fixed to the base l0 of the hoistingapparatus on either side thereof are the hook members 62, to which is fastened the cable 63. l

Pivoted on the which is fixed to wardly.

shan ei is th-yoke 64 the cable 63. lFrom the floor 23 for use after a.

y is then necessar either the v hoisting will'be seen that lengthening or shortening "the cables. 63 will permit vmovement of 'the arm` 54 on its pivot. I

TW hen the cable l63 is leiigthened the'arms 54 willbe' moved to the position shown in dotted ,lines on 'Figure 6V ofthe drawings. By permitting such movement the line of may be engaged for a substantially great area onl either side of. a direct linev between the hoisting` and dumping mechanisms. When ,the arm 54 is swungy substantially a half revolution', the cable 63v isk fastened to the hook member 62 on the opposite side of the base l0 4of the hoisting mechanism.' 'It Y'to remove the cable 45 and turn it over, so that it will work on the pulley'wheels 59 and l60, even though the arm hasbeen swung substantially 180 degrecs. n l The advantages of this device can readily be seen"beca'use'i tlienecessity of moving or ldumping kdevices is to a minimum, while material and .a -widearea'maybe loaded. f Some changes'vmay be Vmade in the construction and arrangement ofthe various parts of my device, without ldeparting from 'the real spirit and purpose of myk invenconstruction of the l'parts just described it ytravel of the'y slip 29 will be varied so that Vearth or vsand ported thereon,ra dump; having upright members, rearwardly inclined brace members, an inclined hoor having `at its upper Vend a downwardly inclined extension, side walls on said extension, a pulley supported at the upper pait of said dump above the highest'part of said inclined floor, a slip,
